That said, if the word "landlord" organically fell out of favor and out of usage to be replaced by something else I wouldn't care. Language is always evolving, and usually we don't make a big deal out of it. It's mundane and can often be helpful. It doesn't have to become a proxy for culture war arguments if we don't make it one.
But to have Google (or any AI) in charge of this... just... no. Admittedly that's a common stance for me but I think it's well justified here anyway.
